C++ language Game | Carrom Board Game
Overview:
Firstly our
game is designed in visual studio using c++-language and graphics are added by
using Open GL. In the start of game the Carrom Board with all the coins at
their arranged positions appear. The task of players/user is to pocket all the
coins of their selected colors. The compiler tells the players during playing
that which color’s turn is that by showing statement “White side’s Turn”.
The player
has to strike the coins with the striker whose position, angle and striking
rate is controlled by the player. The main aim is to finish the coins of
required color as early as possible. The striking properties i-e angle position
and etc. are selected by seeing the position of coin to whom we have to hit.
The game
also provides an interesting option of selection of number of players i-e in
the start it is asked that whether you two want to play or four. In case of two
players the competition is to pocket the coins of their own color. When there
are four players then two teams are generated and each team has to pocket their
selected color’s coin. The Queen coin is higher in rank than all other and has
to be followed by another coin during pocketing.

In the
preview the working window of game id shown in which the black and white
circles represents the coins. The skin colored large circle represents the
striker and the three lines with striker are movable and represents the
direction of striking. The meshed circles are pockets at the corners and the
light skin colored square box is the main playing area. The dialog at the right
side is allocated for instructions and information. This dialog also has two
selection buttons which are “Back” to go to main menu and to “Quit” button to
end game.
Menu:
The main
Menu of the game shows the buttons of various choices i-e. 2
Player, 4 Player, Rules &
How to Play. You can select the operation of your choice by just
clicking the statement shown on screen.
By clicking on the "How to Play" Button you see a screen describing the way of playing and "Rules" shows the rules of game:
Main Working Functions of Game:
First task
is the arrangement of the coins on the carom Board. This arrangement comprises
of the queen coin in the center and others arranged in the form of a circle
outside it. This function is performed by the function “SetFlower” which is as
under.
void SetFlower(float angle)
{
for (int i = 0; i < 20; i++)
{
Coin_Active[i] = true;
}
static float angle_local = 3;
angle_local += angle;
posX[1] = 350;
posY[1] = 350;
posX[11] = posX[1] + 28 * cosf(angle + PI / 3);
posY[11] = posY[1] + 28 * sinf(angle + PI / 3);
posX[12] = posX[1] + 28 * cosf(angle + PI);
posY[12] = posY[1] + 28 * sinf(angle + PI);
posX[13] = posX[1] + 28 * cosf(angle + 5 * PI / 3);
posY[13] = posY[1] + 28 * sinf(angle + 5 * PI / 3);
posX[14] = posX[1] + 56 * cosf(angle);
posY[14] = posY[1] + 56 * sinf(angle);
posX[15] = posX[1] + 56 * cosf(angle + PI / 3);
posY[15] = posY[1] + 56 * sinf(angle + PI / 3);
posX[16] = posX[1] + 56 * cosf(angle + 2 * PI / 3);
posY[16] = posY[1] + 56 * sinf(angle + 2 * PI / 3);
posX[17] = posX[1] + 56 * cosf(angle + PI);
posY[17] = posY[1] + 56 * sinf(angle + PI);
posX[18] = posX[1] + 56 * cosf(angle + 4 * PI / 3);
posY[18] = posY[1] + 56 * sinf(angle + 4 * PI / 3);
posX[19] = posX[1] + 56 * cosf(angle + 5 * PI / 3);
posY[19] = posY[1] + 56 * sinf(angle + 5 * PI / 3);
//now
black coins
posX[2] = posX[1] + 28 * cosf(angle);
posY[2] = posY[1] + 28 * sinf(angle);
posX[3] = posX[1] + 28 * cosf(angle + 2 * PI / 3);
posY[3] = posY[1] + 28 * sinf(angle + 2 * PI / 3);
posX[4] = posX[1] + 28 * cosf(angle + 4 * PI / 3);
posY[4] = posY[1] + 28 * sinf(angle + 4 * PI / 3);
posX[5] = (posX[14] + posX[15]) / 2;
posY[5] = (posY[14] + posY[15]) / 2;
posX[6] = (posX[15] + posX[16]) / 2;
posY[6] = (posY[15] + posY[16]) / 2;
posX[7] = (posX[16] + posX[17]) / 2;
posY[7] = (posY[16] + posY[17]) / 2;
posX[8] = (posX[17] + posX[18]) / 2;
posY[8] = (posY[17] + posY[18]) / 2;
posX[9] = (posX[18] + posX[19]) / 2;
posY[9] = (posY[18] + posY[19]) / 2;
posX[10] = (posX[14] + posX[19]) / 2;
posY[10] = (posY[14] + posY[19]) / 2;
}
The flower of the coins is shown in the picture below:
The main
work in the game is the movement of the striker and coins under the force
applied, friction and the gravitational force.
if (MenuSelect == 3)
{
if (button == GLUT_LEFT_BUTTON && state == GLUT_DOWN) //Click
{
Left_Click_Press = true;
}
}
if (button == GLUT_LEFT_BUTTON && state == GLUT_UP)
{
if (MenuSelect == 3)
{
Left_Click_Press = false;
Shoot_Striker();
printf("mouse clicked \n");
printf("\nmouseX: %d mouseY: %d, State: %d", mouseX, mouseY, state);
}
The above function moves the striker when the left mouse
button is released after pressing. Now the following code of a function will
decide with how much force the striker will be fired.
void Shoot_Striker()
{
if (Left_Click_Press_Duration != 0)
{
{
float Power =
Left_Click_Press_Duration * 900;
float X = mouse_X - posX[0];
float Y = mouse_Y - posY[0];
float angle = atan2f(Y, X);
VX[0] = Power *
cosf(angle);
VY[0] = Power *
sinf(angle);
Moving = true;
Left_Click_Press_Duration =
0;
}
}
}
The following code will decide and check for the
collision of coins with each other and it also checks for that the striker
should not strike behind its position as it is a foul.
void Collision_Check(){for (int i = 0; Moving ? i < 20 : i < 1; i++)if (Coin_Active[i]){Coin_Active[i] = !Pocket_Check(i);if (i == 0)radius = 25;elseradius = 14;OutOfBounds_Check(i, radius);StrikerCollide = false;for (int j = i + 1; j < 20; j++)if (Coin_Active[j]){float CollideDistance = 0;float distance = Distance(i, j);if (i == 0)CollideDistance = radius + 14;elseCollideDistance = radius * 2;if (abs(posX[i] - posX[j]) <= CollideDistance && abs(posY[i] - posY[j]) <= CollideDistance)if (distance <= CollideDistance){if (Moving){if (i == 0){if (Foul_BaseLine == false){Foul_BaseLine = Foul_BaseLine_Check(j);}if (FirstCoinCollision == 0)FirstCoinCollision = j;if (j == 1)Queen_Touch = true;else if (j <= 10)Black_Touch = true;else if (j <= 19)White_Touch = true;}Perform_Collision(i, j, distance, CollideDistance);}else if (i == 0){StrikerCollide = true;}}}}}
